What might the phenotypes be of two organisms that were found to have different genotypes but the same phenotype?
Denka13
Phenotypes refer to the visible traits (or characteristics). Genotypes are the underlying causes for those traits. There may be different genotypes that cause the same phenotype. If the observable traits from one individual are the same from another individual, one can say they have the same phenotypes.

Which can you physically see genotypes or phenotypes?
You can see the phenotype. A good way to remember is that a photograph is what you see. The genotype is the graphic representation of the trait.
Is it true or false that a natural selection acts on phenotypes not genotypes?
It doesn't. Phenotypes are viable or not in a given environment, and this influences whether the corresponding genotypes get passed on. Selection works on genotypes via the effects of their expression, their phenotype. The answer you may be looking for is that phenotypes maladapted to their environment have less babies, and pass on less copies of their genes. "Natural selection" is the whole process over generations. "Selection" may refer to misadapted bodies/phenotypes reproducing less due to illness, hunger, bad quality territories, dying earlier, etc.
Is hair type a genotype or a phenotype?
The genotype is the combination of genes, for example, one inherited brown hair gene is a B (dominant), and one blond hair gene is a b (recessive). The possible genotypes in this example are BB, Bb, and bb. A phenotype is the real-world description of the trait, so the phenotypes for the genotypes listed above would be, in order, brown, brown, and blond. obviously, this is a simplified example. Possible phenotypes for hair color vary widely, and are ever natural color of hair possible: black, brown, light brown, blonde, red, strawberry blonde, etc.
What are variations in terms of evolution?
Normally variations might be differences in genotype between individuals. However, in evolution, the genotype isn't important; rather, the phenotype is what interacts with the environment. In other words, two organisms can have different genotypes (seeming variation), but be equally fit to survive because their phenotypes are the same. Therefore, variation in an evolutionary sense would be differences in phenotype, the outward appearance or function of a trait.
How can you have the same phenotype but a different genotype for a trait?
well GG and Gg both produce the same phenotype for a trait GG and Gg are both different kinds of genotypes that make the same phenotype
How can you have the same phenotype but different genotype?
Different genotypes don't always change your phenotypes because of mutations
Why does natural selection work on organisms phenotypes rather than their genotypes?
This is backward, natural selection works on genotype not phenotype.
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.

You can see the phenotype. A good way to remember is that a photograph is what you see. The genotype is the graphic representation of the trait.
Is hair a type genotype or a phenotype?
A phenotype. Phenotypes are observable, physical traits. Genotypes have to do with the genetic coding. Since hair type is visible, it is a phenotype.
How are the genotype and phenotype of parents related to the genotype and phenotypes of offsprings?
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
Why does natural selection only work on phenotypes?
Natural selection is based on the environment and on the traits of organisms. Organisms with more suitable traits are more likely to survive until reproductive age, while organisms with less suitable traits are more likely to die before they can reproduce. Most of these traits are genetic traits. The phenotype is the set of all genetic traits. Natural selection is not determined by genotypes, because genotypes are merely an organism's genetic makeup. Only the dominant or somewhat dominant alleles in the genotype will also appear in the phenotype. However, genotypes still contribute to natural selection indirectly in that two alleles in two parents' genotypes which had not appeared in their phenotypes could be inherited such that they are in the phenotype of the offspring.
Why isn't it possible to have more genotypes than phenotypes?
I think you have the question backwards, "Why isn't it possible to have more phenotypes than genotypes?" There are always more or an equal number of genotypes relative to phenotypes. The phenotype for a simple dominant/recessive interaction (for example) T for tall and t for short where TT is tall, Tt is tall and tt is short has three genotypes and two phenotypes. If T and t are co-dominant then TT would be tall, Tt would be intermediate and tt would be short. (Three phenotypes and three genotypes.)
What is the relationship between genotypes and phenotypes?
a phenotype is the exterior expression of a predisposed genotype, ie. hair colour. These are both due to the genetical makeup of the parent cells.
Physical characteristics of organisms are called?
Traits (scientifically known as phenotypes)
Can two organisms have different genotypes but the same phenotype?
One way is if an allele for the gene in question is dominant. Homozygotes for the dominant allele and heterozygotes will both have the same phenotype.Organisms have the same phenotype, or physical characteristics. They do not, however, have the same genotype, or genetic makeup. If T represent tall, and t represnts short then the organism will have the genotypes TT and Tt. If you make a Punnett square you will have the same phenotype but different genotypes. Unless some weird mutation occurs....
Can two horses have the same phenotype but different genotypes?
yes.
